I think the decimetre gets used quite a lot, at least in France. We
don't seem to use it at all.

The Range sells net curtains by the decimetre, but they don't brag
about it.

Most fabrics are sold (retail) in multiples of 10cm, FWIW. I don't often
see it
referred to as a decimetre though

No, it is convention to use powers of 1000 - so:

1/1,000,000
1/1000
1
1000
1,000,000


That's why modern rev counters are calibrated as 1, 2, 3 x1000 rpm rather
than the older standard of 10, 20, 30 x100 rpm. (Coupled with that, having
two gauges calibrated 10, 20, 30 - 80 is ripe for confusion.)

So 10 cm rather than 1 dm.

100 m rather than 1 hm.
